so i use Sony Vegas Pro 9.0e. recently, i recorded some new clips in CoD4 with demos. i use Sony Vegas for multiplying the speed of the video by 4 to make the speed back to normal speed. now usually, i could just drag the video to the workspace but now it just stopped working. it shows me the not allowed sign everytime i try dragging it as the mouse cursor. even when i try to open a clip, sony vegas freezes on me, then unfreezes. once it unfreezes, i can finally open the file and then it takes time to be added [5 - 10 seconds most of the time]. i am using Windows 7 Ultimate 32-Bit and Sony Vegas isn't run in compatibility mode. i've tried it before, same problem.
